i'm a house wiring newbie, but i'm slowly figuring it out. figured out a 4-way light switch (that was fun) but this one has me stumped:
my house was built in '82. i have a regular outlet near the kitchen sink that the home inspector said should be a GFCI. when i removed the outlet i found 3 wires on it, black, white and red. the white and red are on the top screws and the black is on the bottom on the red side.
how do i wire this for the GFCI? since the red and black are already connected, do i just wire nut them together with a third wire (black) and run that to the "LINE BLACK" screw, then the white wire goes to the "LINE WHITE" screw?
